Product details
Overview
PK22DN512VLK5 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 core microcontroller with DSP extensions, operating up to 50 MHz, featuring 512 KB program flash, 64 KB RAM, and industrial temperature range (–40 to 105°C). It integrates USB OTG, dual SPI/I²C, four UARTs, 16-bit SAR ADC, 12-bit DAC, real-time clock, and low-power timers - deployed in motor control, industrial sensing, and smart metering systems.
For engineers reviewing the PK22DN512VLK5 datasheet, PK22DN512VLK5 pinout, PK22DN512VLK5 application, or PK22DN512VLK5 equivalent, key selection considerations include flash size (512 KB), FlexMemory absence, 80-pin LQFP package, –40 to 105°C operation, and USB full-/low-speed On-the-Go support with on-chip transceiver.
Technical Context
The PK22DN512VLK5 implements an ARM Cortex-M4 core with hardware DSP instructions and no FPU, running at up to 50 MHz with a 25 MHz flash clock. Its memory subsystem includes 512 KB of program flash (no FlexNVM), 64 KB SRAM, and 4 KB FlexRAM only on FlexMemory variants - excluded here per part number decoding ('N' = flash-only).
Clock architecture supports multiple sources: 3–32 MHz main crystal oscillator, 32 kHz RTC crystal, and multi-purpose clock generator (MCG) with FEI/FBE/BLPE modes. Power management includes eight low-power modes (VLPR/VLPS/VLLS0–3), with VLLS0 current as low as 0.359 µA (POR disabled) at 3.0 V and –40 to 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M4 with DSP, no FPU - enables deterministic signal processing in real-time control loops |
| Max Clock Frequency | 50 MHz - delivers 62.5 DMIPS and 1.25 Dhrystone MIPS/MHz for embedded compute tasks |
| Flash Memory | 512 KB program flash only (no FlexNVM) - sufficient for complex firmware with bootloader, stack, and application code |
| RAM | 64 KB SRAM - supports large buffers, RTOS heap, and real-time data acquisition without external memory |
| Operating Voltage | 1.71–3.6 V - compatible with single Li-ion, 3.3 V rail, or wide-input DC-DC converters |
| Temperature Range | –40 to 105°C - qualified for under-hood automotive, industrial PLC, and outdoor metering environments |
| USB Interface | Full-/low-speed On-the-Go controller with integrated transceiver - eliminates external PHY for host/peripheral reconfiguration |
Pinout & Package
PK22DN512VLK5 is housed in an 80-pin LQFP package (12 mm × 12 mm, 0.5 mm pitch), compliant with JEDEC MO-152AC. Pin assignments follow K22 signal multiplexing defined in the K22 Sub-Family Data Sheet Rev. 4.1, with dedicated functions for USB DP/DM, ADC inputs, PWM outputs, and JTAG/SWD debug.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VSS, VSSA | Power and ground rails | Separate digital/analog supplies reduce noise coupling; VDDA must track VDD within ±0.1 V for ADC/DAC accuracy |
| USB0_DP / USB0_DM | USB differential data pair | On-chip transceiver supports full-/low-speed signaling; requires 27 Ω series resistors and 1.5 kΩ pull-up on DP for device mode |
| ADC0_SE0–ADC0_SE15 | Analog input channels | 16-bit SAR ADC with programmable gain and hardware averaging - suitable for precision sensor front-ends |
| PWM0_A0–PWM0_B7 | Motor control timer outputs | Eight-channel PWM module supports complementary outputs with dead-time insertion for 3-phase inverter gate drives |
| JTAG_TMS / JTAG_TCK / JTAG_TDI / JTAG_TDO / SWD_DIO / SWD_CLK | Debug interface signals | SWD preferred over JTAG for reduced pin count; both support flash programming and real-time debugging |
Key Features
| Feature | Design Value |
|---|---|
| Low-power timer with 32 kHz source | Enables wake-up from VLPS/VLLS modes every 1–65535 ms without CPU intervention |
| Hardware CRC module (32-bit) | Accelerates firmware image validation and communication packet integrity checks in <1 µs |
| DMA with 63 request sources | Offloads CPU from peripheral-to-memory transfers - critical for high-throughput ADC sampling or UART streaming |
| 12-bit DAC with buffer | Generates analog control voltages (0–VDDA) with monotonicity and <±1 LSB INL for closed-loop biasing |
| Real-time clock with battery backup | Maintains time across power cycles using VBAT supply; supports alarms and periodic interrupts |

FAQ
What is the maximum operating frequency of the PK22DN512VLK5?
The PK22DN512VLK5 operates at a maximum core/system clock frequency of 50 MHz. This is achieved using the internal MCG in FEI or PBE mode with appropriate PLL configuration. The flash clock is limited to 25 MHz, requiring wait states above that rate. All timing specifications in the K22P80M50SF4 datasheet are validated at this 50 MHz limit for the PK22DN512VLK5 variant.
Does the PK22DN512VLK5 include FlexMemory (FlexNVM/FlexRAM)?
No, the PK22DN512VLK5 does not include FlexMemory. The 'N' in the part number denotes "program flash only", confirming the absence of FlexNVM and limiting FlexRAM to zero. It provides 512 KB of main program flash and 64 KB of general-purpose SRAM - distinct from 'X'-suffix variants like MK22DX256VLK5 which integrate FlexNVM and 4 KB FlexRAM.
What package type and pin count does the PK22DN512VLK5 use?
The PK22DN512VLK5 uses an 80-pin LQFP package (12 mm × 12 mm, 0.5 mm pitch), identified by the 'LK' suffix in the part number. This package provides full signal access including USB DP/DM, all ADC channels, multiple UART/SPI/I²C interfaces, and JTAG/SWD debug pins - enabling comprehensive peripheral utilization without ball-grid complexity.
Is the PK22DN512VLK5 supported by modern NXP development tools?
Yes, the PK22DN512VLK5 is fully supported by NXP's MCUXpresso SDK, IDE, and Config Tools. Although originally launched under Freescale, it is included in the K22 SDK v2.x and later, with drivers, middleware (USB stack, FreeRTOS), and example projects validated for PK22DN512VLK5. Legacy CodeWarrior projects also remain functional via compatibility layers.
What is the USB capability of the PK22DN512VLK5?
The PK22DN512VLK5 integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver - supporting device, host, and OTG roles without external PHY components. It complies with USB 2.0 specification, includes charger detection (DCD), and supports control, interrupt, bulk, and isochronous transfer types - essential for HID, CDC, and MSC class implementations in the PK22DN512VLK5.
